Background: Twelve-lead electrocardiography ( ECG) is the most important source for the early diagnosis of an acute myocardial ischemia. However, its diagnostic value when the sequence of ventricular activation is altered by ventricular pacing is unknown. The aim of the study was to evaluate the ECG changes on the paced ECG during percutaneous coronary intervention (PCI) by doing temporary pacing.
